Comment (by rmottola):

 Unfortunately, on 10.13 a gcc12 build is not enough:


 {{{

 a gcc13 build instead fails with:


 {{{

 /opt/local/libexec/gcc13/libc++/include/c++/v1/__chrono/duration.h:257:51:

       |
 }}}

 not very promising...

 A buildl with clang 11 yields lot of these warnings:

 {{{
 /opt/local/var/macports/build/_opt_local_var_macports_sources_rsync.macports.org_macports_release_tarballs_ports_graphics_poppler/poppler/work/poppler-24.03.0/utils/pdfdetach.cc:197:26:
 error: 'path' is unavailable: introduced in macOS 10.15
         std::filesystem::path basePath = savePath;
 }}}

 anyone did build popler < 101.15 ??
